Miniature Orange

Dwarf Orange tree

They need four hours of full sunshine or VERY bright light each day to grow and ripen their fruit.
Allow the plant to approach dryness before watering. Keep the soil moist, but never saturated.
Dwarf Citrus have a shallow, spreading root system, so when you are growing them in a container a wide diameter is far better than a deep one.
Citrus trees prefer light, well-drained soil that is rich in nitrogenous food like manure or leaf mold.
Citrus plants need to be grown in acidic soil. If the leaves turn yellow, the soil needs to be made more acid. To maintain the acidity of the soil, dissolve one half teaspoon of magnesium sulfate (epsom salts) into one quart of room temperature water.
Use this solution every two or three months.
Dwarf Citrus should be fed with a complete acid type fertilizer (Rhododendron food) every three months.
In Autumn, fruiting age citrus should receive plant food rich in Phosphorus and Potassium to promote flower development and fruit growth.
The idea growing temperature range for Dwarf Citrus trees in the home is 68° to 75° F.
During the summer months, be sure to provide ample water.

Dwarf citrus trees require periodic repotting about every third year or so.
The dwarfing characteristics of Miniature Orange are the result of keeping the tree root bound in the container, so do not used too large of a planter.
When repotting, use a fresh mixture of one-third peat moss, one-third sand, and one-third sterile potting soil.
Citrus trees respond well to pruning. Keep all the dead branches pruned off, and thin the plant to the three strongest trunks.
